Having a disability does not mean you cannot ride a motorbike or trike. Like cars, motorbikes can be adapted for disabled riders. The National Association for Bikers with a Disability (NABD) provides information about the types of adaptations available to meet different needs.
If you’re disabled, you can use a motorbike/sidecar combination for the motorcycle practical tests. Your licence will be limited to riding this combination.
There are various motorbike modifications that can help people with physical disabilities to ride safely.
